Hertel 64136203 Chucking Reamer 2.5mm Solid Carbide

Product Description

The HERTEL 64136203 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a 2.5 mm (0.0984 inch) reamer diameter, a 4-flute straight configuration, and a bright uncoated finish, this tool delivers accurate, repeatable results in CNC and manual drilling setups. The straight cylindrical shank seats cleanly in standard drill chucks and collets. Diameter tolerance is held to 0.0000 to 0.0002 inches, making it well suited for close-tolerance bore work where surface finish and dimensional accuracy are critical. Right-hand cutting direction is standard for conventional machine spindle rotation.

This chucking reamer is intended for use in machine tool environments including CNC machining centers, drill presses, and engine lathes. It is sized for small-diameter bore finishing in ferrous and non-ferrous materials where solid carbide construction provides the rigidity and wear resistance needed to maintain tolerance over production runs. The compact overall length of 2.25 inches makes it practical for tight clearance setups. Machinists and toolroom professionals specify this reamer for precision fit bores in fixture plates, bearing housings, and close-tolerance assembly components.

Key Features

• 2.5 mm (0.0984 inch) diameter with tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• Solid carbide construction provides high rigidity and wear resistance compared to HSS alternatives
• 4-flute straight configuration for smooth cutting action in through and blind holes
• Bright uncoated finish suitable for a wide range of workpiece materials
• Straight cylindrical shank for secure seating in chucks and collets
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a direct-fit chucking reamer for use in standard drill chucks and collets accepting a straight cylindrical shank in the 2.5 mm diameter class.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and the tool is securely seated in the chuck or collet before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this reamer for material removal beyond its intended finish-reaming function, as overloading a small-diameter carbide tool can cause breakage.
